Claims. 1

My invention relates to animprovement in a casing support for a meat processing unit through which meat is adapted to be passed for tenderizing.

This application is a division of application Serial No. 37,776, filed July 9, 1948.

A feature resides in providing means for receiving the processing unit which includes a casing adapted to support the processing unit and also house an electric motor transmission unit within the casing.

It is a primary feature of my invention to provide a casing which is adapted to receive the processing or tenderizing unit into operating position to contact the transmission unit by holding the processing unit with one end thereof resting on a receiving shelf in the casing and rocking the other end into position in a recess in the casing in which keystone-like shoulder means receive the ends of the unit as it is rocked into operating position. In this position the tenderizing unit is locked in place. The tenderizing unit can be removed in reverse manner by a rotating movement which lifts one end of the unit out of the keystone-shaped shoulder means, and as this end of the processing unit is raised the other end of the unit is released from the drive transmission, coupiers and shoulder means.

It is an important feature to provide casing means for supporting the processing or tenderizing unit so that it can be engaged by one hand of the operator to lift it out of operating position by a simple rotating movement or which may be inserted into operative position by a rotating movement with one hand. Thus I provide a simple means of handling the processing unit so that the free end of the same can be lifted from a locking recess (which is keystone-shaped) and through this lifting movement of the free end of the unit, the other end of the unit is disengaged from the key clutch of the transmission driving unit and the shoulder means.

It is a further feature to provide a casing which will support a removable tenderizing and processing unit for meat and food, the unit being composed of two sections, each of the sections being provided with a shaft upon which are mounted a series of tenderizing knives held spaced apart. The knives of the respective sections overlap and fit between each. other when the sections are assembled as a unit.

It is also a feature to provide a casing support for a processing and tenderizing unit, the unit having means of handling the sections of the unit together on one end of a key which permits the sections of the unit to be rotated toward and away from each other in separating the sections entirely from each other and which holds the sections in line with each other on one end and which leaves the other end of the sections free to be separated or to be moved adjacent each other against bearing faces of the end frames of the sections which hold the sections in line vertically when the same are held as a unit within the supporting casing for operation.

An additional feature resides in means for supporting one section of the processing unit in the supporting casing so that it can be operated by the power coupling means and permit the operator to sharpen the blades of the single section. My construction allows either section of the processing unit to be held separately in the recess of the supporting casing, or the sections may be held as a unit when in processing position within the supporting casing.

A further feature of my invention residesin providing a casing in which is formed a central recess having a bottom forwardly inclined declivity or chute wall, the ends of the recess joining this wall to form a smooth closed casing at each end of the recess which provides the recess with a smooth surface throughout its entire form which can be readily cleaned when the processing unit is removed from the casing. I also provide a hinged cover for closing the central recess and which forms a protective means over the top in front of the processing and tenderizing unit when the cover is closed. However, the forwardly inclined wall is spaced from the lower free end of the cover to provide a chute-like opening out of which the tenderized food or meat drops when it leaves the tenderizing unit.

It is also a feature to provide a cover with a longitudinal slot and depending from the slot is a flange which forms a chute-like opening extending downwardly toward the processing unit which guides meat or food to the unit.

It is also an additional feature to provide a casing formed of a single piece which conceals the electric motor and transmission driving unit wherein the central recess is formed to receive the tenderizing unit with shoulders at each end of the recess upon which the ends of the tenderizing unit rest. One of the shoulders receives the end of the tenderizing unit in first engagement, together with clutch engagement in the casing, and the other of the shoulders receives the free end of the tenderizing unit as it is rocked into operative position in the casing. As a result of my construction the recess may be wiped The invention will appear more clearly iron}.

The unit receivingrece ss 1 has shelf 12 formed longitudinally of the rear portion thereof to which is hinged the cover portion l3 which islvirtually flush with theouter casing and completely covers the tenderiz i1r g unit B"w hen the same is closed for operation. The gover l 3 is formed with the meatreceiving slot l3 onthe top portion thereof. I provideaser ies of gears within the housing which are adapted to drive the clutches or coup1ers22. The couplers 22;ar e cuplike in shape and have the engaging teeth 23 formed on the rims thereof. The" recess l l formed inthe outer casing l 0 is finished off inthe upper portion thereof by the end wear or striker etal p a es i4 an 3 w i h define p iq he recess I lfthe plates 24- and 25 being secured by the bolts 26 and 21- respectively. The bolts 2 6 and 21 ,are secured intotheupright'end walls 241' and 2 re iv l .lfhe hii strike plate 9 s fe gned with the he s Qhe-ehaoed.iiie he fs ehir 4 ders 28 and 29 which are adapted to position and maintain the ends of the sections of the tenderizing unit B together. The end striker plate 25 is formed with the shoulders 30 and 3| which en age wi h the. ect ng shou ders -62! formed on the'e nolsof the hand rails 450i the unit B. The shoulders 28 and 29 together with shoulders 3i) and 3| may be formed integrally with the housing I0.

The projecting shoulders 6| are not only in engagement with the shoulders 30 and 3| but rest on the shelf 32 formed between the shoulders 39 and 31' to properly place the unit B in working positionjnthe recess I I in conjunction with the shoulders 28 and 29 and also the horizontal shelf 33. The horizontal shelf 33 which is formed betweepthe lower ends of the shoulders 28 and 29 supports the lower edges of the sections of the processing unit B when the unit B is in operating position in the recess H.

T e motor 213 ma semen:

ated to rotate either of the sections 4| or 42 individually when they are positioned as illustrated in Figures 3 or 4. The unit B is formed with a horizontally projecting shoulder 6| formed on the ends of the hand rails 46 adapted to engage the inclined surfaces 30 and 3! and rest upon the shelf 32 to properly place the unit B in working position in the recess l I The lower edges of the ends of the frame sections 41 and '42 are adapted to rest upon the horizontal shelf 33 when the unit B is in working position in the recess l I.

A further feature of primary importance resides in the manner in which the unit B is automatically locked in the recess H by engaging with the inclined shoulders 2-8 and 29 which engage with the end surfaces of the unit B and by the engagement of the lugs 6| which engage the shoulders 30 and 3| to securely position the sections 4! and 42 while in the recess II in operating position. This means of joining the separable sections 4| and 42 is unique in that it holds the sections together as a unit during their operation of tenderizing meat. It is apparent that when the unit B is removed from the recess H, as illustrated in Figures 1 and 2, the entire recess is accessible for easy cleaning. At the same time the power unit including the motor 20 is cleansed and protected. It is very desirable that a meat tenderizing or processing machine of this character be made absolutely sanitary for complete cleansing and inspection at all times.

When the unit B is removed from the casing support, the sections 4| and 42 may be individually placed under a water faucet to easily and efiectively cleanse the respective sections of the unit. I thus provide a casing support for a processing or tenderizing unit, such as B, which supports the unit for operation in a unique effi cient manner.

Each section of the unit B is provided with an end portion 52 which is an extension of the roller 43 and has the keys 53 which engage with the couplers 22 as one or both sections of the unit B are inserted in the recess H as hereinbefore described.

The invention is not to be understood as reformed on one of said positioning striker plates; a positioning shelf connecting the lower portions of said shoulders; shoulders formed on the other of said striker plates; and a positioning shelf formed between the lower ends of said second mentioned shoulders.

2. In a meat tenderizing machine having casing with a recess formed therein, said recess having two substantially vertical, oppositely positioned end walls; shoulders formed in one of said end walls; a positioning shelf formed between the lower portions of said shoulders; shoulders formed in the other end of said recess; and a positioning shelf formed between said second mentioned shoulders.

3. In a casing for a tenderizing unit consisting of a body portion and a recess formed in said body portion adapted to receive and support the tenderizing unit and having oppositely positioned end walls: keystone-like cam shoulders in each end wall of said recess adapted to engage the tenderizing unit to support the same in said cas- 4. In a casing support for a sectional, readily separable, removable food processing unit having a recess formed integral with said casing: an inclined bottom for said recess, a horizontal shelf formed at the top of said bottom and a cover hingedly supported on said shelf adapted to close said recess; substantially vertical end walls for said recess, and inwardly inclined shoulders projecting from said end walls adapted to support the tenderizing unit.

5. In a casing support for a removable sectional meat tenderizing unit, said casing support having a body portion and a recess formed in said body portion adapted to receive and supstricted to the details set forth since these may be modified within the scope of the appended claims without departing from the spirit and scope of the invention.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is:

1. In a meat tenderizing machine having a casing with a recess formed therein, said recess having two substantially vertical, oppositely positioned end walls; unit positioning striker plates secured in each of said end walls; shoulders port the tenderizing unit, each section of said unit having a recess formed in its lower edge; keystone-like cam shoulders in each end of said recess, a shelf portion connecting the lower ends of said shoulders in each end of said recess, lug means formed on one of said shelf portions adapted to engage the recesses formed in the sections of the unit to separately support each section of the unit in the recess.
